Efficient syntheses of three novel scaffolds for potential β-glycosidase inhibitors were developed: The first consists of a 2,7-dioxabicyclo[2.2.1]heptane derivative, which was prepared by an intramolecular ketalisation. The second scaffold consists of a hydroxylated cyclopentylamine, which could be synthesised stereoselectively from 2-azabicyclo[2.2.1]hept-5-en-3-one. The third scaffold, a 4,5-dihydroxynicotinic
开发了用于潜在 β-糖苷酶抑制剂的三种新型支架的有效合成:第一种由 2,7-二氧杂双环 [2.2.1] 庚烷衍生物组成,该衍生物通过分子内缩酮化制备。第二个支架由羟基化环戊胺组成,可以立体选择性地从 2-氮杂双环 [2.2.1]hept-5-en-3-one 合成。第三个支架是 4,5-二羟基烟酸,可通过一系列取代基定向的邻位锂化作用获得。选定的化合物作为多种糖苷酶的抑制剂进行了测试。发现三种烟酸衍生物是选择性 β-葡萄糖苷酶抑制剂。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
